2024-07-12 15:04:05 There are two methods:
1. Randomly select a COM port on the computer and send characters arbitrarily. You will see the corresponding indicator light on the right light up, and then you will know which port it is.
2. Install the RainbowLink driver. Four port names will appear in the COM list, which are consistent with the port silk screen names on the product.
